Remove the V4L2 AS3645A sub-device driver in favour of the LED flash class driver for the same hardware, drivers/leds/leds-as3645a.c. The latter uses the V4L2 flash LED class framework to provide V4L2 sub-device interface. Signed-off-by:

pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function. Since ISP always uses domain 0, hard-code it in the code when calling the replacement function pci_get_domain_bus_and_slot(). Signed-off-by:

timespec overflows in 2038 on 32-bit architectures, and the getnstimeofday() suffers from possible time jumps, so the timestamps here are better done using ktime_get(), which has neither of those problems. In case of ov2680, we don't seem to use the timestamp at all, so I just remove it. Signed-off-by:

Adds a new uAPI for DVB to use streaming I/O which is implemented based on videobuf2, using those new ioctls: - DMX_REQBUFS: Request kernel to allocate buffers which count and size are dedicated by user. - DMX_QUERYBUF: Get the buffer information like a memory offset which will mmap() and be shared with user-space. - DMX_EXPBUF: Just for testing whether buffer-exporting success or not. - DMX_QBUF: Pass the buffer to kernel-space. - DMX_DQBUF: Get back the buffer which may contain TS data. Originally developed by: Junghak Sung <jh1009.sung@samsung.com>, as seen at: https://patchwork.linuxtv.org/patch/31613/ https://patchwork.kernel.org/patch/7334301/ The original patch was written before merging VB2-core functionalities upstream. When such series was added, several adjustments were made, fixing some issues with V4L2, causing the original patch to be non-trivially rebased. After rebased, a few bugs in the patch were fixed. The patch was also enhanced it and polling functionality got added. The main changes over the original patch are: dvb_vb2_fill_buffer(): - Set the size of the outgoing buffer after while loop using vb2_set_plane_payload; - Added NULL check for source buffer as per normal convention of demux driver, this is called twice, first time with valid buffer second time with NULL pointer, if its not handled, it will result in crash - Restricted spinlock for only list_* operations dvb_vb2_init(): - Restricted q->io_modes to only VB2_MMAP as its the only supported mode dvb_vb2_release(): - Replaced the && in if condiion with &, because otherwise it was always getting satisfied. dvb_vb2_stream_off(): - Added list_del code for enqueud buffers upon stream off dvb_vb2_poll(): - Added this new function in order to support polling dvb_demux_poll() and dvb_dvr_poll() - dvb_vb2_poll() is now called from these functions - Ported this patch and latest videobuf2 to lower kernel versions and tested auto scan.

When kernel-doc is called with output selection filters, it will be called lots of time for a single file. If there is a warning present there, it means that it may print hundreds of identical warnings. Worse than that, the -function NAME actually filters only functions. So, it makes no sense at all to print warnings for structs or enums. Signed-off-by:
